CNDUlT FOR TRACTlON-ROPE RAILWAYS.

SPECIFICATION forming part of Letters Patent o. 296,667, dated April 8, 1884.

C Application filed February 25, i884. (No model.)

To @ZZ whom it may concern:

Be it known that I, Zircone Paint BOYER, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Conduits for Traction-Rope Railways; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. Heretofore in systems of conduits or tubes used for the purpose of traction-rope or endless-cable railways there have been certain objections-viz., the vast expense of placing the same in the ground in Working order; the difdculty of maintaining the sides so rigidly in position as to check the tendency to collapse, and thus narrow the slot or continuons opening through which passes the rod connectin the car with ythe cable; the liability of the rais to spread for lack of being sufciently braced; the tendency of the conduit to become depressed in places Where the foundation was not quite lirm, and the liability of horses7 shoes to get caught in the sharp angled slotted opening.

The objects of my invention are, by means of a comparatively cheap method of construction of the conduits and their appurtenances and the employment',V of a system of rigid braces, to obvate allsuch objections and overcome all lateral strains. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical cross-section at the point of contact of tivo sections of a conduit or tubing. vFig. 2 is a plan view. Fig. 3 is a longitudinal vertical section of the same, showing the tubing externally, and, Where the same is broken away, the construction and operation of the rolling apparatus.

Similar letters referto similar parts througliout the several views.

A is a rolled girder, of heavy iron or steel, preferably constructed of a T-rail bent into a form approaching that of a horseshoe, with wings extending horizontally therefrom nearly at a right angle, and to and beneath the chairs 5o I), on which rest the sills of track I, said Wings being the support of other parts of the superstructure.

B B are continuous rolled iron or steel beams bolted and screwed or otherwise fasttened by commonly-known means and rigidly secured to the upper flange of the yoke A, as shown at the angle b, and the said beams being constructed, as shown and placed at such a uniform distance apart that the rod or arm of the grip connecting the car with the endless 6o Wire cable may glide along through the slotted opening Without difficulty.

C C are iron or steel rods penetrating beams B B, and connecting them to the chairs D D, which chairs are bolted to the yoke, as Well as at the other end, and thus serve to rigidly secure the track sills and rails to the yoke.

E E represent a tubing formed of wroughtiron or steel plates of any desired thickness, or of vitrified clay, of brick, or other materials 7o suitable for the protection of a traction-cable system.

F F are cast-iron supports or brackets for the sheaves of pulleys on which the cable runs, which supports are bolted and secured to the yoke A, being made to conform to the curvature of the yokeAat the points where secured.

G represents the pulley, and gthe cable running thereon. It will readily be understood that the journals of the pulleys shall be kept 8o lubricated by means of oil-cups, as commonly used.

H H represent a bed of concrete in which the whole structure is iirmly set to the under surface of the upper ilange of the yoke A, and 8 5 on the concrete is placed a layer of sand of suiicient thickness to receive the paving of the roadway.

I I are the rails on which roll the Wheels of the cars. At suitable distances apart there 9o may be man-holes, as in other systems.

Having sufticiently described my improvements, what Iclaim as my invention, and desire to secure by Letters Patent of the United States, is

l. In a conduit for a traction-rope or endless-cablerailway, the iron or steel yoke A, of the form approximately of a horseshoe, and having Wings extending horizontally therefrom at nearly a right angle, forming level 10:1

bearings, as at vb, adapted to receive and support the'nietallic beams B B, said yoke being rigidly held in position by means of concrete, H, all constructed substantially as set Vforth and described. I

e2. In conduits for traction-rope or endlesscable railways, yoke A, formed of a'single T- rail, or any single rail of iron or steel of the shape shown, bent into the form described, for the purpose of encompassing the Walls or sides of the conduit or tubing, and also to serve for rigidly holding in position beams B B, chairs D D, and supports FF, constructed and arranged substantially as specified.
